2. TOLERANCE AND TYPE NUMBER DESIGNATION (V )
Z
The type numbers listed have a standard tolerance of ±5% on the nominal zener voltage.
3. ZENER VOLTAGE (V ) MEASUREMENT
Z
The zener voltage is measured with the device junction in the thermal equilibrium at the lead temperature (T ) at 30°C ± 1°C and 3/8″ lead
L
length.
4. REVERSE LEAKAGE CURRENT (I )
R
Reverse leakage currents are guaranteed and measured at V shown on the table.
R
5. MAXIMUM ZENER CURRENT RATINGS (I
)
ZM
Maximum zener current ratings are based on maximum zener voltage of the individual units and JEDEC 250 mW rating.
6. MAXIMUM VOLTAGE CHANGE (DV )
Z
Voltage change is equal to the difference between V at 100 mA and at 10 mA.
